Enable/Disable CPU Repeat Gard
CPU repeat gard automatically deconfigures a CPU during a system boot if
a processor has failed BIST POST, caused a machine check or check stop,
or has reached a threshold of recoverable errors. The processor will remain
deconfigured until repeat gard is disabled or the processor is replaced.
Repeat gard is enabled by default.
For more information, see “Configuring and Deconfiguring Processors or
Memory” on page 55.
Enable/Disable Dynamic Processor Sparing
This option is part of the Capacity Upgrade on Demand (CUoD) function.
Dynamic Processor Sparing is the capability of the system to deconfigure a
failing (or potentially failing) processor and then configure a replacement
processor from the unlicensed CUoD processor pool.
If the system is running logical partitions, the hot sparing operation takes
place while the system is running. If the system is booted in a full system
partition, the system must be rebooted for the processor sparing operation
to take place.
Processor hot sparing is enabled by default.
Note: The memory affinity of the failing processor is not taken into account
when the replacement processor is assigned; the replacement
processor is the next processor that is available.
This menu allows the user to change the system processor configuration. If it is
necessary to take one of the processors offline, use this menu to deconfigure the
processor, and then reconfigure the processor at a later time. An example of this
menu follows:
